How To Make Mashed Potatoes in the Instant Pot
Prepare the ingredients: Peel the garlic cloves and roughly chop them. Wash and cut the potatoes into chunks that are uniformly approximately sized 1 to 1 ½ inches in size.
Note: The potatoes are not peeled in this recipe. If you prefer your potato skins off, peel the potatoes before cutting them into chunks.
Step 1. Add the ingredients
Place the cut potatoes, water, sea salt, and garlic into the instant pot. Cover and seal the lid and cook on high pressure for 8 minutes of cooking time.
Step 2. Release
Once the timer goes off, let the potatoes slow-release for five minutes. Then carefully press the steam release valve and remove the lid of the instant pot. The potatoes will be cooked, almost falling apart and soft.
Step 3. Mash the Potatoes
Mash the potatoes with a potato masher and add a little bit of butter or milk and a dash of black pepper and serve.
Ingredient Notes & Substitutions
Potatoes. High-starch potatoes such as Yukon gold potatoes (yellow potatoes) or russet potatoes make the best mashed potatoes. The high starch content causes the potatoes to fall apart easily when they are cooked, which makes them easy to mash; perfect for fluffy mashed potatoes.
Fresh Garlic. Fresh garlic adds a delicious flavor to these easy mashed potatoes. Fresh garlic can be replaced with ½ teaspoon of garlic powder added after they are cooked.
If don't want to cook the garlic with the potatoes, you can add a few cloves of roasted garlic when you mash the potatoes with the butter.
Water. If you prefer more flavor to your mashed potatoes, substitute a cup of water with a cup of vegetable or chicken broth.
